Note:
Always
turn off the water supply when the WaterJet is not being used. This prevents
leaks and damage to the water hose and connections.
12. Empty the waste filter (see
).
Note:
If it is necessary to remove support material from hard-to-reach areas and to give the
model a smooth finish, continue by soaking the model in a solution of caustic soda (see
below).
Removing Support Material with Caustic Soda
Note:
Use nitrile gloves to protect the your hands handling caustic soda and models soaked in
it.
To remove thin layers of support material and to give the model a smooth, clean finish, soak the model in
a solution of sodium hydroxide (NaOH, known as
caustic soda)
. For the exact composition of this
solution, refer to the printer user guide.
The amount of time required to soak the model in the solution depends on how delicate it is and how much
support material needs to be removed, but it is typically between half-an-hour and several hours (up to six
hours). In any case, you should remove as much support material as possible before the treatment, and
rinse the model thoroughly with the WaterJet afterwards.
